About This Data
The 1991 Ford Orion has an MOT pass rate of 54.8% based on 1,288 tests — below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 52,711 miles on the odometer. With a 45.2% failure rate, the 1991 Orion is rated as "Poor" for MOT reliability.
If you own or are considering buying a 1991 Ford Orion, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to brakes: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm). At 52,711 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Brakes — 0.8% of failures
Brakes issues account for 0.8% of MOT failures on 1991 Ford Orion models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
Visibility — 0.5% of failures
Visibility issues account for 0.5% of MOT failures on 1991 Ford Orion models. Visibility failures relate to the windscreen, wipers, washers, mirrors, and view-obstructing damage. Cracks in the windscreen swept area, ineffective wipers, or empty washer bottles are common causes. Typical repair costs: £10–300. Pre-MOT check: Check the windscreen for chips and cracks — damage larger than 10mm in the driver's swept area or 40mm elsewhere will fail. Test washers and wipers. Ensure both door mirrors are intact and adjustable.
Body, chassis, structure — 0.5% of failures
Body, chassis, structure issues account for 0.5% of MOT failures on 1991 Ford Orion models. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
